To reset a Scotsman ice maker, first locate the control panel, usually on the top left corner of the machine. Press and release the red button to power down the machine. Then press and hold the green button for one second to automatically reset and power on the machine.
There are a couple of instances in which it may be necessary to restart a Scotsman ice maker, the first being after an internal computer failure. If this is the case, a simple reset should return the ice maker to working order. The second situation that may require a restart is after maintenance. In this instance, resetting the machine finalizes the maintenance process.
If after attempting to reset the machine manually the problem persists, refer to the manufacturer's service manual for further instruction. There are a number of potential problems that doing a simple reset does not resolve. If problems persist, make sure the water line that feeds the machine is good, that the condenser fan blade is clean and that the evaporator plate is not worn.
Scotsman has released a recall on certain models of ice makers built from 2006 to 2009 with faulty electrical components that can be a potential fire hazard. Be sure this is not the issue before attempting a manual reset.
